# DoD Promotes MOSA Technology Refresh

A Military Embedded Systems analysis argues that the Department of Defense’s Modular Open Systems Approach (MOSA) mandate can support lower-cost technology refresh only when programs build functional independence into mission computers and across platforms; compliance with interface standards alone may not deliver that benefit. The article points to the Army’s High Accuracy Detection and Exploitation System (HADES) as an architectural example, pairing a deterministic time-sensitive networking (TSN) backbone with partitioned computing. It identifies no solicitation, award value, or procurement contact, so the information is architectural and market-positioning guidance rather than an active bid opportunity.

- Programs and contractors should distinguish functional modularity and replaceability from interface-standard compliance when presenting MOSA-aligned designs.
- HADES illustrates how deterministic networking and partitioned computing can support a modular ISR architecture; the article provides no contract award or solicitation details for the program.
- Contractors can use the analysis to position technology-refresh capabilities around independent, upgradeable mission-computing components, while recognizing that no specific procurement action is announced.
